LUMA SET

1. Problem Statement

As PHP applications grow, organizing all operations within individual scripts and functions becomes increasingly difficult. Related data and behaviors need clear boundaries so that changes in one part of an application do not create unnecessary dependencies elsewhere. Object-oriented programming introduces classes, objects, inheritance, and interfaces, but these concepts require an understanding of how they work together. Without a consistent design approach, classes can accumulate unrelated responsibilities, while inheritance structures may become difficult to maintain. Application architecture also requires decisions about object creation, dependency relationships, data representation, and communication between components.

2. Solution

Luma Set introduces object-oriented PHP through a structured progression from basic class definitions to application component organization. The curriculum explains how to define responsibilities, manage object state, apply encapsulation, and establish relationships between classes. Dedicated modules examine inheritance, abstract classes, interfaces, traits, namespaces, and automatic class loading. Further topics introduce dependency injection, service components, repositories, data transfer objects, and exception handling. A final applied project brings these concepts together in a small application architecture with defined responsibilities, component contracts, and practical testing scenarios.

3. What's Inside

• Module 1: Object-Oriented Programming Fundamentals
  Introduction to the object-oriented programming model and its role in organizing PHP applications. Examination of objects as combinations of state and behavior, the distinction between procedural and object-oriented approaches, and situations where classes provide a useful organizational structure.
• Module 2: Classes and Object Creation
  Defining classes, creating instances, declaring properties and methods, and working with object references. Study of how class definitions describe object structures and how multiple instances can represent separate entities with their own state.
• Module 3: Properties, Methods, and Visibility
  Working with public, protected, and private members. Understanding how visibility rules influence interaction between objects, how methods represent component behavior, and how properties hold internal state. Practical exercises focus on organizing class members according to their responsibilities.
• Module 4: Constructors and Object Lifecycle
  Studying constructors, initialization parameters, and object creation procedures. Working with the __construct() method, property initialization, default values, and object lifecycle considerations. Introduction to destructor behavior and situations where explicit resource cleanup may be relevant.
• Module 5: Encapsulation and Object Invariants
  Exploring encapsulation as a way to control changes to object state. Defining methods that validate incoming values, protecting internal properties, and maintaining consistent object conditions. Practical examples demonstrate how an object can prevent invalid combinations of values through controlled operations.
• Module 6: Composition and Object Collaboration
  Building complex objects from smaller cooperating components. Examining composition, aggregation, object references, and relationships between independent classes. Learning how responsibilities can be distributed among collaborating objects without creating unnecessarily complicated inheritance structures.
• Module 7: Inheritance and Method Overriding
  Studying parent and child classes, inherited properties, inherited methods, and method overriding. Exploring the extends keyword, parent references, constructor behavior in inheritance hierarchies, and situations where a shared base class can represent common behavior.
• Module 8: Abstract Classes and Shared Structures
  Defining abstract classes and abstract methods to describe shared structures for related classes. Examining which methods must be implemented by child classes, how common behavior can remain in a parent class, and how abstract structures differ from ordinary classes.
• Module 9: Interfaces and Component Contracts
  Creating interfaces that describe methods expected from implementing classes. Working with the implements keyword, multiple interface implementation, and separating component requirements from implementation details. Practical examples show how interfaces support interchangeable components and clearer relationships between application layers.
• Module 10: Traits and Reusable Behavior
  Studying traits as a PHP mechanism for sharing methods across unrelated classes. Exploring trait declarations, trait inclusion, method conflict resolution, aliases, and visibility adjustments. Exercises examine when shared behavior can be extracted into a trait and when composition is a more suitable structure.
• Module 11: Static Members and Class Constants
  Working with static properties, static methods, and class constants. Understanding the difference between object-level and class-level state, using self and static references, and examining late static binding. Practical examples cover shared configuration values and operations that do not require an individual object instance.
• Module 12: Namespaces and Code Organization
  Understanding namespaces as a method of organizing classes and preventing naming conflicts. Working with namespace declarations, fully qualified class names, use statements, aliases, and hierarchical naming structures. Examples demonstrate how related classes can be grouped into logical sections of an application.
• Module 13: Automatic Class Loading
  Exploring automatic class loading through spl_autoload_register(). Examining how PHP locates class definitions, how loading rules relate to namespaces, and how consistent file organization supports class discovery. Practical exercises introduce a simple custom autoloader without relying on external tools.
• Module 14: Enumerations and Value Objects
  Working with enumerations to represent a defined collection of possible states. Studying backed and pure enums, enum methods, and their role in replacing unclear collections of string or numeric values. Introduction to value objects that represent domain concepts such as monetary amounts, identifiers, and status descriptions through controlled data structures.
• Module 15: Exceptions and Domain Error Handling
  Exploring exception hierarchies, custom exception classes, and structured error handling. Working with try, catch, finally, and throw, as well as defining separate error categories for different application conditions. Practical examples demonstrate how components communicate exceptional situations without mixing error handling with ordinary business operations.
• Module 16: Dependency Injection and Object Creation
  Studying dependency injection as an approach to providing objects with the components they require. Examining constructor injection, method injection, dependency relationships, and manual object assembly. Exercises show how explicit dependencies make component relationships easier to understand and allow individual components to be replaced during testing.
• Module 17: Services and Application Responsibilities
  Introducing service classes as components that coordinate application operations. Separating business rules from input handling, persistence operations, and presentation logic. Practical examples cover service methods, operation sequencing, validation responsibilities, and communication between application components.
• Module 18: Repositories and Data Transfer Objects
  Exploring repository interfaces as boundaries between application logic and data storage. Working with data transfer objects (DTOs), object construction from stored records, and conversion between application data structures. Exercises introduce repository contracts and simple implementations that can be replaced without changing the surrounding application logic.
• Module 19: Testing Classes and Component Contracts
  Studying methods for checking object behavior and component relationships. Writing focused test scenarios for constructors, methods, validation rules, exceptions, and interface implementations. Exploring assertions, test data preparation, boundary cases, and the distinction between testing one class and evaluating collaboration between multiple components.
• Module 20: Applied Architecture Studio — Course Registration Manager
  Developing a small PHP application that represents a course registration process. The project includes Course, Learner, and Registration classes, value objects, interfaces, a registration service, repository contracts, and custom exceptions. The implementation demonstrates object composition, dependency injection, state validation, and organized communication between components. The final stage includes test scenarios for registration rules, invalid data, duplicate records, and changes to registration status.
